Signer FirstName and LastName

As it sits, now, there has to be a value defined for First Name, Last Name, and Email to create a signer. All are required. If you pass everything through either First Name or Last Name, you still have to pass something other than a space, null, or empty string to the other. You could definitely request an enhancement for this functionality by posting in our enhancement ideas forum. Our product managers look through there for ideas on new features.
